My wife currently has t-mobile, and can't keep her hands off of my iphone. Her contract is up around the time the new iphone comes out, and will be switching over to AT&T on some kind of a family plan not sure which one yet. My question is can I give her my old iphone when i buy the new one and put her on my account? Where do I get another simcard for the old iphone? Any ideas or suggestions would be helpful.~Chris
